On June 28, 2018 Kymab reported its clinical trial agreement with F. Hoffmann-La Roche Ltd under which Roche will provide its PD-L1 blocking antibody atezolizumab for use in combination with Kymab’s lead investigational anti-ICOS antibody therapy KY1044 in Kymab’s upcoming Phase I/II clinical studies in patients with advanced solid cancers (Press release, Kymab, JUN 28, 2018, View Source [SID1234537005]).

"We have presented preclinical data demonstrating strong synergies between an anti-PD-L1 treatment in combination with KY1044 against multiple tumour types," says Arndt Schottelius, MD, PhD, Executive Vice President, Research and Development of Kymab. "We look forward to the initiation of our first studies and exploration of the potential synergy of our programs for the benefit of patients with advanced solid cancers."
Kymab will be responsible for conducting the clinical trials, and both companies will share data from the trials. Kymab continues to retain all commercial rights to KY1044.
KY1044 is designed to both deplete intratumoral Regulatory T-cells and stimulate T Effector cells to enhance the immune response against tumors.
Kymab plans to conduct a Phase I/II study in a variety of solid tumours both as monotherapy and in combination with atezolizumab. Indications that have elevated levels of both ICOS and FOXP3 might be especially responsive to this combination of checkpoint inhibitors.
Kymab will lead studies to evaluate this hypothesis: atezolizumab, an anti-PD-L1 antibody that acts as a checkpoint inhibitor, and KY1044, an antibody targeting ICOS expression, will be tested for synergistic action to recalibrate the immune response. Kymab plans to initiate monotherapy studies of KY1044 in the first half of 2019 and studies in combination with TECENTRIQ in the second half.

About KY1044
KY1044 is a fully human monoclonal antibody discovered by Kymab’s unique suite of technologies. KY1044 has now been tested in number of highly illustrative syngeneic models, which demonstrate that KY1044 strongly inhibits tumor growth in cancers both as a monotherapy and in combination with other immunotherapies.
Inducible T Cell Co Stimulator (ICOS), is expressed upon activation on T cells and at high levels on the majority of FOXP3+ regulatory CD4+ T cells. Importantly, available data demonstrate that depletion of these immunosuppressive cells from the tumor microenvironment enhances the patient’s anti-tumor immune response.
